EEOZBACCO-Ellfl] application filed July 29,

This invention relates to smokers appliances and more particularly to a tobacco supporting and draft regulating attachment for a pipe.

One objectof the invention is to provide an attachment which may be removably fitted into the bowl of a pipe and support the tobacco above the draft passage of the stem and prevent clogging of the passage and also cause the tobacco to burn evenly when air is drawn through the bowl and stem of the pipe.

Another object of the invention is to perout a tobacco supportimgdisk :t'orming a portion of the attachment to be readily forced downwardly into the bowl of the pipe and have close fitting engagement with the walls thereof and assume a concavo- CQIIVGK shape when in place.

Another object of the invention is to provide a device of this character which may be stamped from pliable sheet metal and very cheaply produced.

The invention is illustrated in the ac companying drawing, wherein Figure 1 is a sectional view showing the attachment applied to a pipe;

Fig. 2 is a perspective view of the attachment, and

Fig. 3 is a view showing the attachment in front elevation before it is applied to a pipe, a portion of its handle being; broken away.

The attachment constituting' the subject matter of this invention is preferably formed of pliable sheet metal, although other materials may be employed and includes a tobacco supporting: disk 1. having a handle or shank 2 extending therefrom. as shown in Fig. 2. The disk 1 is provided with a diametrically extending slit 3 which terminates adjacent the lower end of the shank or handle and divides the disk into eompani on side sections t which are adapted to have their adjacent side portions overlapped, as shown in Fig. 3. A plurality of openings 5 are formed in the side sections of the disk so that air may be freely drawn into the smoke passage 6 of the stem 7 of a pipe having; the attachment fitted into its bowl 8, as shown in Fig. 1. Referring to Figs. 1 and 2, it will be seen that the openings decrease in size from the free ends of the sections 4; towards their joined ends at ATTAGHMENT.

the base or lower end of the shank This causes the air to pass more freely through the portions of the disk farthest from the smoke passage 6 and, therefore, the tobacco will be caused to burn evenly instead of the major portion of the consumption taking placeat the side of the bowl from which the smoke passage and stem extend. The disk is normally slightly larger than the bowl of the pipe with which it is intended to be used but not of sufficient size to prevent it from being; forced downwardly to the position shown in Fig. 1. Pressure applied to the disk in order to force it downwardly into place will cause the adjacent side portions of the sections 4. to slide over each other and at the same time the central portion of the disk will be depressed so that the disk assumes a concave-convex shape. The marp inal edges of the disk will have close fitti ng engagement with the walls of the bowl so that it will be firmly held in place and tobacco and its resulting ashes prevented from working downwardly beneath the disk. The disk is limited in its downward movelllellt by the bill or hook 9 at the upper end of the shank 2 and when in place supports the tobacco above the draft passage 6. It will thus be seen that tobacco pressed into the bowl will be prevented from clogging; the smoke passage and that air may be freely drawn through it. While the suction in the bottom of the bowl is naturally greater at the side thereof from which the stem and its smoke passage extend the provision of the large and small openings in the disk will cause the suction to be evenly distributed in the bowl and the tobacco evenly consumed. After the tobacco has been all reduced to ashes, the attachment may be drawn outwardly through the mo dium of its shank or handle and the ashes will be removed and the walls of the bowl scraped clean. While the attachments are to be made for use in connection with pipes having bowls of approximately the same size, it will be readily understood that, since the disk is slit, it may accommodate itself to bowls which vary somewhat in. diameter.

Having; thus described the invention, I claim:

A tobacco pipe attachment comprising a normally flat disk formed with draft passages, a shank extending upwardly from ing overlapped and adapted to he moved the periphery of said disk, said disk being transversely of each other and bowed to pro- 10 provided with a slit extending diametriduce a concavo-convexed disk when fin-(red cally across the disk and terminating adjainto a pipe bowl.
